Application filed January 3, 1921. Serial No. 434,674.

T 0 all 7mm it may concern Be it known that I, CARL BRAMMING, a

' citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Dash-Lamps, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to dash lamps, and has as an object the provision of a new form of lamp that shall consist of few parts and be simple of manufacture.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which- Fig. 1 is a side view of a dash lamp attached to an instrument board shown in section;

Fig. 2 is a central longitudinal section;

Fig. 8 is a transverse section on the line 3-3 of Fig. 2;

Fig. 1 is a detail central longitudinal sec tion showing a modification;

Fig. 5 is an end view from the left of Fig. 4;

Fig. .6 is a view slightly in perspective, of a locking washer; and

Fig. 7 is a section on the line 77 of Fig. 1.

To make the lamp stand in a horizontal position from a slanting dash or instrument board, or to stand at an angle from a vertical board, the central tube 10 has a portion removed, as at 11, and the remaining portion 12 bent so as to cause the two portions of the tube to stand at the desired angle. A bayonet joint slot is cut in one end ofthe tube, as at 13, for the reception of a bulb of the usual form. A spring plug 14 is placed in the tube, one or more tongues 15 being struck inwardly out of the metal of the tube for the plug to seat upon.

To strengthen the lamp socket, to improve the appearance of the lamp, and to hold the hood 16, a shell 17 is provided. The shell 17 is shown as supported by having its edge turned about a disk 18, which in turn is supported upon tube 10 by means of a flange or collar 19 secured to the tube. Since the disk 18 is not placed at a right angle to the axis of the shell 17, the disk will be elliptical, as shown. in Fig, 7,

Patented Nov. 29, 1%21 The shell 17 is drawn from a flat plate and has an annular end 20, with an opening to fit the tube 10, a seat 21 for the hood lo, a shoulder 22, and a main portion 23 curved outwardly to receive the edge of the disk 18. The hood 16 has a light opening 241, as is usual. The tube 10 is shown as screwthreaded for reception of the clamping nut 25.

In the modification of Fig. 4 a bead 26 is formed by bulging the metal of the tube 10 outwardly and the disk 18 is seated against the head. The end of the tube 10 is passed through the instrument board 27, a lock washer 28 is placed over the tube, and acam nut 29 is tightened on the-tube to hold the lamp in place. To cooperate with the cam nut 29 a pair of lugs 30 are struck out from the metal of the tube 10. The cam nut 29 is preferably formed from a flat plate. The margin is turned up into a polygonal flange 31, and the central portion into a ring or flange upon the edge of which are formed the cam surfaces 32 separated by notches 33 to pass over the lugs 30. iVith the parts in the position shown in Fig. 41, if the nut is revolved the lugs 30 will ride upon the'cam surfaces and clamp the locking washer against the instrument board.

Minor changes may be made in the physical embodiment of the invention without departing from its spirit.

I claim as my invention-- 1. A dash lamp comprising a tubular shell having its base oblique to its axis, an integral tube for holding a connector plug and a bulb base, such tube being bent to bring its end portions respectively normal to the plane of the shell base and parallel with the shell axis.-

2. A. dash lamp comprising a tubular shell having its base oblique to its axis and having an instanding annular flange at each end, an integralplug and bulb-holding tube fitting within the openings in the flanges and being bent to aline its end portions with axes thereof.

3. A dash lamp comprising a tubular shell having its base oblique to its axis and having an instanding annular flange at each end..an integral plug and bulb-holding tube fitting within the openings in the flanges, such tube having a lateral opening extending through more than half of its circumference and hav in g the portion of its Wall opposite the opening bent to aline the ends of the tube with the axes of the flanges.

41A dash lamp comprising, in combination, a tube having a lamp socket at one end thereof, a, securing stem at the other end adapted to project through an aperture in an instrument board, a bend 'on said stem of greater diameter than said aperture, a pair 10 of lugs on the projecting portion of stem and a cam nut coacting With said lugs.

CARL BRAMMING.
